摘要: 目前单管绝缘栅双极型晶体管(IGBT)的耐压能力还不足以满足高电压大功率整流器、逆变器、柔性输电等场合的需求。IGBT的串联使用是一种提高耐压能力的有效方法，解决均压问题则是实现IGBT串联应用的关键。本文详细分析了IGBT动态关断过程，并结合关断过程对栅极驱动信号延时导致的串联不均压机理进行了分析，在此基础上提出了一种基于栅极控制的IGBT串联动态均压控制方法，通过延长密勒平台和抑制集射电压斜率实现串联动态均压，并给出了该方法的电路结构和工作原理。在MATLAB/SIMULINK平台仿真验证了该方法的有效性和可行性。
Abstract: At present, the voltage withstanding capacity of single insulated gate bipolar transistor (IGBT) is not enough to meet the needs of high voltage and high power rectifier, inverters, flexible trans-mission and other occasions. Series use of IGBT is an effective way to improve the voltage with-standing ability. Solving the problem of voltage equalization is the key to realize series application of IGBT. In this paper, the dynamic switching process of IGBT is analyzed in detail, and the mecha-nism of series unbalanced voltage caused by the delay of gate driving signal is analyzed. Based on this, a grid-controlled IGBT series dynamic voltage balancing control method is proposed. The dynamic voltage balancing in series is realized by extending Miller platform and suppressing the slope of collector voltage. The circuit structure and the working principle are given. The simulation on MATLAB/SIMULINK platform verifies the validity and feasibility of this method.
